Title: Improvements in Intaglio Printing Presses.
IPC: B41F13/00
Filed: 1919-04-08
Abstract: 134,479. Goss Printing Press Co., (Goss Printing Press Co.). April 8, 1919. Driving machines; tripping-arrangements; inking-apparatus.-In an intaglio perfecting machine, the impression cylinders mav be tripped separately or in unison, and tripping operates automatically to disconnect the main drive and permit a secondary drive from the driving motor to rotate the printing cylinders at a reduced speed, whereby inking is maintained. The motor 68 drives the machine through a pinion 69 gearing with a wheel 71 normally clutched to its shaft 72, which drives through bevel gearing a shaft 77. This shaft carries bevel wheels gearing with bevel wheels 79, 82 having ratchet-driving connexions with shafts 80, 83 extending across the machine and geared with the intaglio printing cylinders 20, 21. Another wheel 77<a> on the shaft 77 drives through shafts 67, 64, and 61 the mechanism for slitting, superposing, and folding the web 51 after printing. The printing cylinders rotate in ink containers 22 which are vertically adjustable by screws 24 operable through bevel gear and crossshafts from hand-wheels 25. The impression cylinders 29, 30 are mounted in sliding bearings 31 yieldingly carried by springs 33 and bolts 34 from blocks 32 in which the head of a bolt 35 is swivelled. These bolts have screwed engagement with worm-wheels 36, which may be rotated simultaneously through cross-shafts 39 and a longitudinal shaft 46 from hand-wheels 42 for simultaneous adjustment of the impression cylinders, and have further key engagement with worm wheels 37 which may be operated by worms from cross-shafts and hand-wheels 43 for independent adjustment of the cylinders. When the cylinders are tripped individually or simultaneously, a lug 100 on the bearing 31 acts through a rock lever 98, rod 101, bell-crank, horizontal spring-pressed rod, and rock-lever to disengage the clutch connecting the shaft 77 with the wheel 72, thereby stopping the machine. The motor continues to run and drives the printing-rolls at a reduced speed through a wheel 89 and worm-gear 91, 92 which is connected to a shaft 93 through a ratchetwheel drive, this shaft driving the shafts 80, 83, from which the printing-rolls are driven, through worm gear 94, 95.
Patent GB-411260-A (GB)
Title: An improved process for stabilising organic esters of cellulose
IPC: C08B3/28
Filed: 1933-03-24
Abstract: Organic esters of cellulose made by the nonsolvent method in the presence of a catalyst, such as sulphuric acid, capable of combining with the cellulose, are stabilized by extracting the catalyst and/or compounds thereof with cellulose by means of an alkyl ester, fatty acid or mixture of both, if necessary in the presence of a diluting liquid such as benzene, which is a swelling agent for the cellulose ester.  For example, there may be used ethyl acetate, amyl acetate, ethyl acetate and acetic acid, or ethyl acetate and formic acid.  The stabilizing treatment may be carried out immediately after the manufacture of the cellulose ester, while the latter is still in a swollen state.  In an example, cellulose acetate containing 3 per cent of sulphuric acid obtained by acetylating linters with acetic anhydride in the presence of benzene and sulphuric acid, is washed with hot benzene-glacial acetic acid (5 : 1) and subsequently heated with benzene-glacial acetic acid (8 : 2), washed with benzene and dried.  The product contains less than 0,01 per cent of sulphuric acid.  In another example, the cellulose acetate used above is separated from the acetylation liquid, washed with alcohol denatured with benzene, heated up to boiling point, and extracted with hot alcohol containing 15 per cent of glacial acetic acid.  In a third example, linters are acetylated in the presence of ethyl acetate as non-solvent, drained, and heated with a mixture of ethyl acetate and glacial acetic acid (85 : 15).  The cellulose esters are preferably transformed into cakes under pressure prior to purification, and the liquids then forced through them.  The process may be applied to the tri-esters or to other esters, for example, to acetates soluble in acetone.  The products are used in the manufacture of filaments, films, capsules, and the like.

Title: Improvements in electrical resistors comprising a ceramic support and wire wound thereon
IPC: H01C17/065
Filed: 1942-07-03
Abstract: 579,735. Wire resistances. EXPRESS LIFT CO., Ltd., PARTRIDGE, J. H., and WELLS, L. E. W. July 3, 1942, No. 9200. [Class 37] [Also in Group XXIII] Resistance wire wound on a ceramic body is covered with vitreous enamel which binds it to the ceramic and has a coefficient of expansion somewhat less than that of the ceramic so that at room temperature the enamel is mostly or wholly in compression. The enamel used should not require for its application to the wire-wound ceramic body a temperature higher than 1000‹C. A suitable enamel comprises 40 to 55 per cent. of silica, 25 to 35 per cent. of boric oxide, not more than 6 per cent. of sodium or potassium oxide, and from 10 to 15 per cent. of barium oxide, strontium oxide, zinc oxide, titanium oxide, lead oxide, and fluorine. Small quantities of other substances such as arsenic oxide or nickel or cobalt oxides may be added. The solid powdered enamel is applied in stages to the ceramic made hot enough to melt the enamel when it comes into contact with it, the progress of the enamelling being continually observed. After the enamel has been applied to the wire-wound ceramic body the surface may be cooled by forcing a strong current of air over the surface of the enamel, so that when the enamel sets the temperature of the ceramic body is considerably greater than that of the enamel.

Abstract: 762,218. Potato harvesters. CAIRNS, W. R. and SOUTER, J. S. March 30, 1955 [March 30, 1954], No. 9236/54. Class 6(3). [Also in Group II] A machine for separating potatoes or other substances from stones or other refuse material comprises an endless belt conveyer 8 having flexible spreader flaps 12 travelling transversely of the conveyer of which the delivery end is disposed above the delivery end of an endless belt separator A. Flexible flaps 14 are provided between a second separator B and separator A which has its delivery end above a transverse conveyer 16. Linkage for adjusting the inclination of the separator A is operable by independent levers 29, 31, Fig. 3. In Fig. 4, which shows the spreading conveyer and separators as seen from the opposite side of the machine, a cable 36 attached to one side frame 18 of the spreading conveyer enables that side, and simultaneously the corresponding sides of the separators A and B, to be raised or lowered. In addition, the rear end of the spreading conveyer 8 is adapted for raising or lowering and the inclination of separator B may be adjusted by means of a further lever, Fig. 5 (not shown). As shown in Fig. 1, the separating machine forms part of a potato digger or harvester, the potatoes, earth, stones and other material being pushed over a share 1 on to a chain elevator 2 through which most of the earth and small stones fall. After any shaws and potato haulms have been separated by an endless extractor 4, the potatoes and other material are deposited in a drum screen 6 and then carried by a conveyer 7 on to the spreading conveyer 8 where they are spread over the whole width thereof. Most of the other material passing on to the separator A from the spreading conveyer is discharged over the rear end of the separator on to a transverse conveyer 13 for disposal at the side of the harvester. The potatoes, however, roll on to a separator B after being checked by the flaps 14, and finally roll rearwardly off separator B on to a transverse conveyer 15 ready for loading. The remaining material discharged over the front of the separator is carried away by conveyer 16. The inclination of the separator A is adjusted to compensate for conditions when the harvester is moving uphill or downhill and the raising or lowering of the sides of the spreading conveyer and the separators A, B permits the harvester to work on uneven ground.
